I have joined the Department of Software at Sungkyunkwan University as an assistant professor in August, 2012. My research area is Cyber-Physical Systems (CPS) that are computing systems interacting with physical, real environments. I am leading Cyber-Physical Systems Laboratory at Sungkyunkwan University. My research includes (i) CPS supporting the safe and efficient driving in transportation systems (e.g., road networks) in real life and (ii) CPS protecting and monitoring efficiently transportation systems (e.g., road networks and subways) and people (e.g., drivers, passengers, and pedestrians) in emergency situations (e.g., wars, accidents, and disasters).

I worked for Brocade Communications Systems from 1/19/2010 to 8/1/2012 (two and a half years) as a software engineer. I designed and developed IP Security (IPsec) modules for the gateway (called 7800 and DCX) for interconnecting Data Centers.

I have a ten-year-old son whose name is Younseong (born on February, 2003) and a five-year-old daughter whose name is Younjee (born on May, 2008). My son's hobby is Taekwondo that is a Korean martial art. He is a very active and lovely child and likes to listen to fairy tales and gospel songs. My daughter is a lovely little girl and smiles brightly with her eyes.

My family's photos are as follows: The first one is my family, December 2010. The second one is my son and daughter, December 2010. The third one is my wife, Younkyeong and me at the promotion test, May 2012. The fourth one is me, May 2012.

Hobby and Community Service

My hobby is to play classical guitar. My favorite guitar piece is "Duo in G". In the future, I would like to play this piece with my children.

I am teaching Taekwondo (Korean martial art) to children including my son in Minneapolis.

I coached the youth soccer team in CTC that is the University of Minnesota Graduate Student Housing in August, 2009.
